Abstract: In the title compound, C₁₈H₂₀N₄O₃·H₂O, the two aromatic rings are linked through a methylidenehydrazide fragment, which is fully extended with C-C-N-N, C-N-N=C and N-N=C-C torsion angles of 179.4 (2), 174.7 (2) and 178.3 (2)°, respectively. The dihedral angle between the two aromatic rings is 7.01 (8)°. In the crystal structure, the water of hydration is involved in extensive hydrogen bonding. Intermolecular O-HO, N-HO and O-HN hydrogen bonds link the components of the structure into a two-dimensional network and additional stabilization is provided by weak intermolecular C-HO hydrogen bonds.
